Description

Technical Field

[0001] The utility model relates to the technical field of inertial measurement devices, in particular to a sensor inertial measurement device. Background Art

[0002] Inertial sensors are sensors that measure acceleration and angular velocity through conservation laws. They are usually made using micro-electromechanical systems (MEMS) technology. Inertial sensors usually include a mass block, microsprings, sensing electrodes, and support structures. When the inertial sensor is affected by acceleration or angular velocity, the mass block causes the microspring to vibrate, thereby generating a voltage signal, which is finally converted into a digital signal output.

[0003] For example, an inertial sensor described in the patent document with announcement number CN221652936U provides a connector on the bottom cover plate, which enables the bottom cover plate to be easily installed on the cover shell for disassembly, thereby improving the efficiency of assembly and disassembly. The matching design of the fixing seat on the bottom cover plate enables the inertial sensor of this scheme to be easily adjusted, so that it is suitable for installation and use on mounting holes of mounting objects of different sizes. This inertial sensor engages two sets of connectors and then pulls a buckle ring to disassemble the cover shell. Therefore, it is inconvenient to quickly disassemble the cover shell, which reduces the maintenance efficiency.

[0004] Based on this, a sensor inertial measurement device is now provided, which can eliminate the disadvantages of the existing device. Utility Model Content
